Process for granulating lead chromate-containing pigments

A process for the production of high yields of nondusting, free-flowing granules of a lead chromate-containing pigment composition, which process comprises (a) forming an aqueous slurry of a lead chromate-containing pigment dispersed in a friable hydrocarbon resin having a Ring and Ball softening point within the range of 50.degree. to 75.degree. C. and a number average molecular weight range of 500 to 900 by agitating said pigment and resin in water in the presence of a cationic surfactant at a temperature above the softening point of the resin, said pigment and resin being present in a weight ratio from 7:1 to 1:1 and said resin and surfactant being present in a weight ratio of from about 2.5:1 to about 3.5:1, (b) continuing agitation of said slurry at a temperature within the range of from about 5.degree. to about 20.degree. C. above the softening point of said resin until the pigment dispersion is granulated and (c) recovering the resulting granules.
